The amount of time we spent looking at screens was increasing naturally, but the last year of lockdowns has catalysed the process. We now spend so much time on phones, laptops and televisions that digital eye strain is becoming a real issue that needs to be addressed. Fortunately, SmartBuyGlasses have the perfect solution. They have created technology called zFORT™ that acts as a filter on glasses to block out the blue light emitted from digital screens. This does wonders for your eye health, and it is affordable and accessible to all. Bear in mind, you don’t need to have a prescription to get blue light glasses – just get the coating added to a plano lens!
What is blue light?
Sunlight is composed of different coloured rays. There is orange, red, yellow, blue, and green. Each ray of light has different levels of energy and its own wavelength. Compared to the others, blue light rays have much shorter wavelengths, ranging from 380nm to 500nm, and have extremely high levels of energy. It has now become common knowledge that these blue light rays can be greatly harmful to the human eye.
Pros and Cons of Blue Light?
You may be surprised to hear that blue light isn’t all bad. We need some blue light in our lives to improve our memory and mood. It also helps us regulate our sleeping patterns, and is vital to children’s eye health development. So really, we’d be quite lost without it! It only becomes a problem when we are overexposed to blue light.
So, we must not get carried away with the positives. At the other end of the scale, blue light remains harmful. Excessive exposure to blue light, such as looking at a screen for extended periods of time, has the potential to cause severe damage to your eyes. The most common symptom of overexposure to blue light is digital eye strain. This takes the form of headaches, difficulty sleeping and can lead to mental health issues. It is therefore of the utmost importance that we protect our eyes from too much blue light.
What is zFORT™ ?
zFORT™ blue light block technology was recently introduced at SmartBuyGlasses. It is a blue light filter that prevents the blue light wavelengths from penetrating the eye’s retina. Once you have chosen your glasses and lens type, you can add the blue light coating on top, whether you have a prescription or not. The filter will be added to the lenses, and the blue light glasses will arrive on your doorstep ready to wear. It is also a very affordable solution to the dangers posed by blue light.
Why buy zFORT™?
No matter who you are, health is always a top priority. So why put your eyes at risk when you can so easily keep them safe? After all, sight is one of the things we want to protect the most. So here are three key benefits to the zFORT™ blue light filter:
- Continuous exposure to blue light rays can lead to eye strain. Eliminate the risk by adding zFORT™ to your glasses.
- zFORT™ reduces your eye’s contact with blue light, which is crucial when working, gaming, online shopping, watching TV etc. Essentially, when doing anything that requires the use of a digital screen.
- Protect your eyes from blue light and notice the difference when you go to sleep at night! The reduction in blue light exposure will help you sleep much better.
